Pedal Powered Zeolite (Vacuum) Refrigerator. which provides it with increased mobility. • The new refrigerator created is independent of power grid. Pedal-Powered (Vacuum) Zeolite Refrigerator. The refrigerator works by creating a vacuum in a system of 2 chambers to drive a thermodynamic reaction (boiling. 16 Nov Pedal-Powered (Vacuum) Zeolite Refrigerator – YouTube any tried it before? i was just wondering if i can replace the Zeolite to just simple.

There were also some concerns related to the use of methanol, since it is toxic. The continued pedalling will ensure that the water freezes as it continues to boil.

And pecal we have to do a lot pedal powered zeolite refrigerator testing over the equipments and machinery for the complete manufacturing of our project Pedal Powered Zeolite Refrigeration.

Subscribe To Posts Atom. Hence I decided to choose refrigeration as a field for our final year project, which will be an alternative to the conventionally used refrigerator, a project in which simplification of present tech is involved to get cooler water, with less power consumption so that a common man can have an access to it. In the designed refrigerator, zeolite is the adsorbent and methanol can be treated as refrigerant. This was what motivated the third year Engineering student from BEC College, Bagalkot, Karnataka, Narendra Patil to come up with this interesting model of a refrigerator.

This is surmounted by a 50 cm. Certainly pedal powered zeolite refrigerator is no way to pedal powered zeolite refrigerator two bottles of milk, some Coke, and a roast of beef freezing cold. Initially we built the Evaporator unit of GI-sheet, without internal support.

pedal powered zeolite refrigerator Back in college we used to have our practicals in workshops, where we used to get exhausted by the time we finished.

Narendra tells us proudly:. There are also many other essential purposes that such refrigerators could be utilized for apart from storing food, as Narendra points out. Victor Papanek described this in his book Design for the real world: With further modification and up gradation, Narendra hopes that the refrigerator could be used in remote areas with pedal powered zeolite refrigerator access to power. One, that of necessity and two, that of the environmental degradation that it can cause by consuming power and emitting CFCs chlorofluorocarbons into the ozone layer, thus depleting it and leading to global warming.

In general, one can achieve constant temperatures of Celsius for 1 day with only 10min of pedaling. The limitations that they are working on include the low COP values, poor heat and mass transfer problem that poses a bottleneck to prevent the improvements of adsorption refrigeration technique, intermittently working principles, high technology requirement and special designs pedal powered zeolite refrigerator maintain high vacuum.

An alternate adsorbent-adsorbate pedal powered zeolite refrigerator selection can easily solve this problem. After only about 10 min refrigeratoe pedaling, the valve to the vacuum pump can be shut off, and the zeolite container line opened.

The major items required were not available in their district. There is research going on the solar powered adsorption refrigeration. There is a baseboard unit that includes a tyre pump, a heat exchanger, a pump, pump valves, and a metering valve, as well as a hand crank. Click here to access the Project Report, and view their video here.

Pedal powered zeolite refrigerator of their efforts were wasted too as the few apparatus they had bought refrigerztor were hydraulic valves and not pneumatic valves. The Hurdles Once the design refriverator put on paper, the real challenge lay in actualizing it with instruments, apparatus and raw materials. We live in the North geographical zeolte of Karnataka, where temperature is usually high in summer degrees celsius.

The refrigerant used, methanol, is environmental friendly since it is not a hazardous substance. Ipsita Sarkar is a freelance writer.

pedal powered zeolite refrigerator The reason behind its cost zeolote is its zero power consumption and no requirement of fossil fuels to burn the planet in the process of cooling.

Have you added Founders Circuit app to your account? The adsorbing phase is the adsorbent, and the material concentrated or adsorbed at the surface of that phase is the adsorbate.

TBI Innovations: The Mechanical Fridge – Freezing Environmental Damage

Ramani 6 years ago. In order for the liquid water to remain in equilibrium with the vapour phase, it must continue to boil. For cooling, continue pedaling is required. It is zeolie remarkable technological offering that has made our lives a lot cooler.

Our Project Guide was happy to pedal powered zeolite refrigerator the results and appreciated our hard work. Problems Identified Time consuming Leakage problem through pipes Improper working of Refrigeraor Proper lubrication is required This system only works when vacuum is created.

That said, they are their own critics and perfectionists. Clearly, what is required is a neutral zone wherein a refrigerator is available pedal powered zeolite refrigerator all, yet with minimal adverse environmental impact.

Limitations While confident about the pros of his refrigerator model, Narendra and his team simultaneously hope to address the cons of the model as well, to achieve the pedaal possible efficiency.

Pedal Power Zeolite Refrigeration. There pedal powered zeolite refrigerator other challenges too and corresponding modifications done.

The idea started off as their topic for the final year project. Share this content on your social channels.


It forces hot pressurised air through a heat exchange which returns the air to near-ambient temperature. Later we chose copper sheet with internal support.

Response and Road Ahead The model completed, there were felicitations and applause from every corner. Follow us facebook twitter instagram youtube.

We developed a hand-cranked, modular produce cooler. They defrigerator research papers and supporting documents in the seventh semester. Even with exams nearing and project deadlines refrlgerator large over their heads, they pedal powered zeolite refrigerator from store to store and went that extra pedal powered zeolite refrigerator.
